Abstract

Tax competition theory predicts that the introduction of the EU Single Market in 1993 should have caused excise tax competition and thus increased strategic interaction in the setting of excise taxes among EU countries. We test this prediction using a panel data set of 12 EU countries over the period 1987-2004. We find that for excise duties on still and sparkling wine, beer and ethyl alcohol, strategic interaction significantly increased after 1993. There is weaker evidence of increased interaction in cigarette taxes, possibly because cigarettes are widely smuggled, giving rise to tax competition even before the Single Market.
